Should solar energy projects prioritize total annual generation volume or generation timing to match demand?
Polish developer MODMEC has announced plans to expand its dual-axis solar tracking system into the U.S. market. A domestic test installation of the technology demonstrated a 36.1% weighted average increase in energy output compared to fixed-tilt systems.
Why it matters
The system is designed to address the "duck curve" challenge by capturing more solar energy during late-afternoon hours, which helps optimize the timing of battery storage charging.
The system demonstrated a 36.1% weighted average increase in energy output compared to fixed-tilt systems. Developers project the tracking solution will deliver 11% additional energy after 4 pm when compared to standard single-axis systems.
The players
MODMEC
A Polish solar developer specializing in row-based dual-axis tracking hardware and software optimization.
Kinematics
A supplier of motion control and drive systems utilized in the MODMEC tracking technology.
The details
The MODMEC solution uses a row-based architecture that eliminates the need for a central mast by employing independent row-level controls. These controls allow the system to adjust panel orientation using drives supplied by Kinematics. The hardware is paired with an optimization software layer called Smart Watts to manage solar tracking. The system design is protected by a Polish patent, with a U.S. patent application currently pending.
Timeline
Energy production is projected to increase by 11% in the window after 4 pm.
The Tech Race
The MODMEC system seeks to outperform the current industry-standard single-axis solar trackers by utilizing dual-axis movement at a row-based level. This approach directly challenges the established single-axis dominance by aiming for higher energy capture in the late-afternoon power window.
The technology is currently intended for utility-scale deployment through U.S. engineering, procurement, and construction partnerships rather than direct consumer purchase. Its adoption may influence the efficiency and charging cycles of utility-scale battery storage systems in the near future.
The takeaway
This system highlights the growing industry focus on maximizing energy production specifically during evening peak hours to balance storage demands. Stakeholders should watch for the announcement of the company's first U.S. pilot project partners to gauge the viability of this dual-axis approach in the American market.
